You are implementing a Windows Communication Foundation (WCF) client application that consumes the ICatalog and lCatalog2 service interfaces.You need to ensure that the client discovers services implementing these interfaces. The services may already be online or may come online within a 30 second time limit. How should you use WCF Discovery to accomplish this？（）

A. Create one FindCriteria object for each interface and set the Duration of each FindCriteria to 30 seconds. Call the FindAsync method of the DiscoveryClient class twice, one time for each of the FindCriteria objects, to search for the services.

B. Create one FindCriteria object for each interface and set the Duration of each FindCnteria to two seconds. Create a loop that calls the Find method of the DiscoveryClient class to search for the services. Within each loop iteration, call the Find method of the DiscoveryClient class once for each of the FindCriteria objects. Run the loop until a service is found or 30 seconds pass.

C. Create a single FindCriteria object and add both interfaces to its ContractTypeNames collection. Set the criteria‘s Duration to two seconds. Create a loop that calls the Find method of the DiscoveryClient class to search for the services. Within each loop iteration, call the Find method of the DiscoveryClient class to search for the services Run the loop until a service is found or 30 seconds pass.
